This invention relates to an apparatus for taking out cream from milkcontainers. It consists of a small container of rigid or semi-rigidmaterial with upwardly directed walls, open above and in the bottom, avalve adapted to close the bottom opening of the small container andbars or other means so connected with the container or the valvethat thecontainer may. be manipulated and the valve opened and closed froma'placelocated outside the container; Preferably the apparatus consistsof .a cylinder with bottom valve. The invention aims particularly atexecuting an apparatus or this kind insuch a way that the manufacture issimpleand reliable, while at the same time theoperation is satisfactory;Particular stress has been laidon producing the individual parts of theapparatus by stamping out from metal sheets. It seems then mostconvenient according'tothe invention to hinge the bottomvalve on thelower edge of the cylinder instead of having it fixed directly to a barwhich can be moved up and down. Prefer- .ablythebottom valve isprovidedwi-th inclined projection which turns to the side in such a waythat'it can be swung together with the valve proper by' the end ofaneedle which slides along the cylinder at its outer end; The saidprojection is providedwith 'twoprotruding, horizontal pivotswhich gettheir bearing lug on the lower edge of the cylinder: The cylinder issplit longitudinally and the split edges are bent outwards and backwardsthrough about 180; The needle which serve s to open or-closethe valve isguided by a guideforming a channel which has arr-approximately circular,but open, section, and may be thread upon the split edges of thecylinder in such a way that it grips round same so a to close thecylinder along the split;

One embodiment is illustrated in the drawing, in which Fig. l shows avertical-section through the apparatus. Fig 2 shows a cross section onthe line 22 in Fig. 1, Fig. 3 an elevation of" the cylinder itself inunmounted state, Fig. 4 is a cross section onv the line .44..in Fig. 1,and Fig. 5 is a plan view of the bottom valve alone.

The cylinder is bent from a uniformly thick metal sheet, conveniently ofbrass, so that it assumes a cylindrical shape, split longitudinally at 2(see Fig. 3). In this condition, the cylinder is somewhat larger than itwill be when the various parts of the apparatus are assembled. The,Split edges .of this cylinder are bent back approximately through 180,as shown at 3 in. Figs. 3

and 4, and corresponding. thereto a gu de 4 is used for the needle onrod 5', which operates. the valve. This guide 4 is also. bent togetherfrom a relatively long metal strip into an approximately cylindricalchannel, as will be seen from Figs. 2 and 4. The longitudinal edges donot quite meet, and the distance between them is so "by its own weight.

In this state the. guide can be slid down along the-sides. of the.cylinder and will consequently close the cylinder-at thesplit .2,whereby theparts. assume themutual position shown in Fig. 4. The guidefurthermore has a pair of members. band .I, ofwhich 6 isopen at theside, while l is perforated for the. penetration of. the needle .5. Thelatter is. passed by the cylinder I: and. .pro jects at 5':below thebottom-of the cylinder, where it is: adapted to act! iona tongue .8projecting from the bottom valve 9. This is-a'lso. stamped out fromsheet metal and is circular in shape so as to fit against the loweredge. of the cylinder 1 closed toward the guide 4.

This cylinder is at the bottom provided with two-bearing lugs ID for.projecting pivots i I. on the bottom valve 9. These bearing lugs: are inthe unattached state-of the cylinder 1 at. such a distance from eachother that it. is possible :withoutdifficulty to-pushthe pivots H into,po sition. But when the. cylinder 1- is closed by pushing down the guidet, the bearing lug l0 'wil'liibe moved so 'closely together that theywill engageapproximately the-side edges: of the. proj'eotion a andthereby lock, the hinge connection between the bottom valve- 9: and: thecylinder 1 so as to preventremoval of the valve. This position :of'thebottom valve will be seen Fig. I- where the projection B- hasan inclinedposition downwardsrelatively to the horizontal bottom valve 9 In thevposition shown in- Fig. 1', the end 5 0f the needl'epresses against theprojection 82 and thereby keep the bottom valve 9 closed.

Ti on the other hand the end 5" of the needle is drawn up a little inits guide-bymeans of the ring handle at the top, the needle end 5" willrelease the projection 8, whereby the bottom valve 9 will swing downinto a vertical position In this condition the apparatus can-be insertedinto the top of" a milk bottle to a suitable depth, so that the topportion of cream enters; into the cylinder. t. Then the needle 5 ispushed down by means of the handle, so that the value is closed,whereupon the apparatu is lifted out with they cream.

The various. parts of the apparatus may also e pro uced .01" othermaterials than metal, viz. plastic, press material etc,

For sanita y p rp ses the apparatus is so designed. that the. individualpartscan easily be taken apart for cleanin For the same. reason the useof closed pipes is avoided, which would havehad to be soldered or.welded the apparatus, whereby rests; of. milk. or cream. might easilypass up into the closed parts and get contaminated if an efiectivecleansing were difficult or impossible.
